Recommended Fermentation Temperature Range:

  • 20 C to 27 C (68 F to 80 F)

14 days at 71 F in 1045 sweet wort, Ph 5.6

  • Apparent Attenuation–89%

General Brewing Notes & Guidance:

Lactic Acid Bacteria are inhibited by hops, high gravity and low temperatures. You can adjust sourness by increasing or decreasing these variables. More than 7 IBU, gravity above 1050 or temps below 18 C (65 F) will increase the time to sour or lead to reduced overall souring. Warmer fermentation temps will typically increase the esters and spicy phenolics of the saison ale yeast in this blend.
